Research format challenge has a start date and an end date. Innovators have the full duration to submit the solutions. The administrator can add a buffer (keeping the challenge open for last minute participants to submit their solution).

Staggered Time format allows innovators to attempt the challenge in a specific time slot between the specified start date and end date of a challenge. For example: You can host the challenge from Jan 1 until Jan 3. The innovator(s) would have a specific time (with timer) within that time to do the work. Example 3 hours from the time they start working till submission time.
